I have a small crack forming around the front of the fin box on the under side of the board. I was thinking of digging it out a little with the dremel and filling with it epoxy to re-seal the board, then keep a close eye on it. Hopefully there is nothing too bad underneath and the seal holds - otherwise I have some deeper surgery to do...

Has anyone done a similar repair or should I be taking this to a professional?

Cheers
Brett
